SSL certificates some times maybe pain on the xxx.
i used webmin and usermin with Almalinux with Let's Encrypt
Test Tools i use
- https://www.checktls.com/TestReceiver (for smtp)
Certificate #1 of 2 (sent by MX):
Cert VALIDATION ERROR(S): self signed certificate
So email is encrypted but the recipient domain is not verified
result T or F
what is a good valid way to issue an SSL certificate for smtp and web ?
